Real talk though; we need to face the facts about dieting for weight loss.

On any specific approach over the long term, more people are
unsuccessful than are successful. On all approaches combined, more
people are unsuccessful than are successful. However... while successful
outcomes are the minority, they are not exclusive to any specific
approach.

What can we observe or logically conclude about what enables a person to be successful with any approach to dieting?

I suggest the following:

They enjoy & have an appetite for enough of the included choices
of food that they are satiated, or at least that hunger levels are
manageable.

Total energy intake is far enough below "an
excessive" level that would preclude fat loss, but high enough to avoid
or mitigate adaptive thermogenesis aka "starvation mode" in the common
vernacular.

Ideally they're including a suitable amount of
reasonably healthful and nutritious choices, but some famous "stunt
diets" you may have read about prove it could be done on just potatoes,
twinkies, macdonalds, ice cream & whey... whatever. None of which I
would personally recommend but it demonstrates an important point.

The eating habits they adopt fit in with their lifestyle &
circumstances, and they're able to stay enthusiastic and not gravitate
back towards their old habits.

So their are any number of overly
simple answers but the reality is that for most people, success is going
to be something that you have to decide upon and keep working on, on an
ongoing daily, weekly, monthly, seasonal, year in, year out basis.
Therefore you want "the path of least resistance" in my opinion.

Now... people often attempt to 'splain to me that their personally
prefered diet (usually LCHF) is "more satiating" and therefore
preferable over brute force starvation approaches which work in theory
but backfire long term due to the effects on metabolism.

You can
refer to the above for what is wrong with this logic. It would be
satiating IF you happen to enjoy enough of the foods that fit this
eating style and happen to consume enough of them to meet that "adequate
but not excessive" energy provision that results in weight loss without
metabolic adaptation.

However if you DON'T happen to enjoy enough of
those foods, then it actually does become a brute force deprivation
based approach. I still don't really understand how people can be quite
so low in emotional IQ that they can't grasp this concept.

ANYWAY let's wrap this up.

With the right guidance you could achieve that "adequate but not
excessive, satisfied but not stuffed, weight loss without metabolic
downgrade" eating pattern on ANY selection of foods without feeling
afraid or guilty about ANY particular choices or needing to rule
anything out (other than on specific medical grounds obviously).
